6 FAQs about [Stirring positive and negative electrode materials of lithium battery]
What is electrode slurry?
The resulting suspension is referred to as the electrode slurry, which is then coated onto a metal foil, i.e. Al and Cu foils for positive electrodes and negative electrodes, respectively.
What makes a good electrode slurry?
From a processability perspective, the ideal electrode slurry would be capable of being coated at high speeds with few defects. Among the most common industrial coating instrumentation is the slot-die coater, in which the slurry is transferred through a slot gap onto a moving substrate.
How can rheology be used to evaluate the stability of electrode slurry?
Among the best methods to appraise the stability and processability of an electrode slurry (and, therefore, the effectiveness of the homogenization procedure) is by characterizing its flow behavior via rheology. Liu et al. have introduced basic rheology concepts in the context of LIB electrodes .
Why does a Li-ion electrode have a higher internal resistance?
This weakens the mechanical integrity of the coating and leads to a higher internal resistance within the electrode [17, 100, , , , , , , , , , , , , ] because binder acts as a barrier for Li-ion insertion.
Can slurry rheology predict electrochemical performance?
Slurry rheology alone cannot predict electrochemical performance. Optimal coating drying rate is sensitive to the underlying drying mechanisms. Next generation electrode manufacturing needs to minimize or eliminate solvent. Tailored electrode architectures will unlock the lithium-ion battery’s potential.
What is lithium-ion battery manufacturing?
As modern energy storage needs become more demanding, the manufacturing of lithium-ion batteries (LIBs) represents a sizable area of growth of the technology. Specifically, wet processing of electrodes has matured such that it is a commonly employed industrial technique.
